PURPOSE:To realize the uniform directivity within the horizontal surface between the input and output terminals, by tilting the opening faces of several electromagnetic horns provided to the phase center axis vertical to the electric field axis of the reflector surface against the horn axis. CONSTITUTION:The primary electromagnetic radiation horns 21-24 are distributed on the phase center axis vertical to the electric field axis of the fan-shaped beam antenna reflector 1. Then the cut angle is provided to the horns 21-24 in correspondence to the position of attachment, and as a result the directivity within the horizontal surface can be made uniform between the input and output terminals. |
